Baseball great, Rollie Fingers is a former MLB relief pitcher who played for the Oakland Athletics (1968–76), San Diego Padres (1977–80) and Milwaukee Brewers (1981–85). In addition to Rollie Fingers pitching ability, he was noted for his handlebar moustache which he originally grew to get a $300 bonus from Athletics owner Charles O. Finley. Although most former A's players shaved their handlebar moustaches off after the team traded most of their players in 1975-76, Fingers maintained it after being traded to the Padres in 1977 and still has the moustache today.

Fingers was one of the first players groomed in his minor league career to be a relief pitcher once he reached the majors. His former owner with the Athletics, Charles O. Finley, was one of the first to do this. Prior to this, most pitchers were starters first and foremost and usually ended up in the bullpen by either necessity or afterthought. Rollie Fingers's number 34 was retired by the Oakland Athletics in 1993 and by the Milwaukee Brewers in 1992. Rollie Fingers is one of only eight players who have had their numbers retired from more than one team.
